A cryogenic tank for storing cryogenic fluids is disclosed. The cryogenic tank is typically configured to be mounted on a vehicle for supplying cryogenic fuel to a propulsion system of the vehicle. The cryogenic tank comprises an inner vessel for containing cryogenic fluids and an outer vessel surrounding the inner vessel to define a vacuum insulating volume therebetween. The outer vessel is configured to transmit static and/or dynamic loads, while the inner vessel is partially or completely isolated from such loads.

Process and plant for the production of liquid hydrogen with a liquefier that has a variable cooling power dependent on the electrical power consumed. The liquefier is supplied with electricity by a first source of electricity at least one additional source of electricity that provides an intermittent or variable amount of electricity over time. Liquid hydrogen is produced at first thermodynamic conditions when the liquefier is supplied with a predetermined nominal electrical energy level and produced at subcooled conditions, with respect to the first thermodynamic conditions, when electricity supplied to the liquefier exceeds the nominal level.

Fuel gas supply system for supplying a high-pressure gas injection engine with gas stored in a liquefied gas tank, preferably an LNG tank, having a high-pressure pump to which liquefied gas is supplied. The system including a condenser with a high-pressure heat exchanger, a high-pressure vaporizer which is connected to the high-pressure pump via the high-pressure heat exchanger and is arranged downstream of the condenser. Gas fed to the high-pressure gas injection engine downstream of the high-pressure evaporator. A compressor to which boil-off gas is fed is connected downstream to the condenser via an inlet. A condensation core generator to which liquid gas is supplied from the high-pressure pump in such a manner that the condensation nuclei generated by the condensation nucleus generator promote condensation of the supplied boil-off gas. The liquid gas formed in the condenser is supplied to the high-pressure pump and/or to the liquid gas tank.
